“…PUDs were synthesized from vegetable oil-based polyol by following the formerly reported procedure 17 as described in detail in our previous work. 42 First, the measured amount of cottonseed oil-based polyol was mixed with the DMPA and homogenized in four-neck flask equipped with a mechanical stirrer, reflux condenser, nitrogen inlet, and thermometer. The reaction was carried out at 80 C for 30 min then IPDI was added within the next 30 min, and at the same time dibutyltin dilaurate was also added and preceded the reaction for 3 h. The viscosity of the reaction was controlled by the addition of methyl ethyl ketone.…”

One of the major challenges facing the polymer industry now is finding sustainable and renewable alternatives to petroleum-based raw materials. To overcome such challenges, these novel water-borne polyurethane dispersions were prepared from bioresources (vegetable oil). Vegetable oil-based polyol is synthesized by epoxidation and hydroxylation methods from vegetable oil. Consequently, polyurethane dispersions are prepared by reacting the vegetable oil-based polyol with isophorone diisocyanate and dimethylol propionic acid to form the polyurethane prepolymer, which further reacts with 1,4-butanediol, and the final product is obtained by the addition of water. Fourier transform infrared analysis is used for the structural confirmation of the prepared vegetable oil-based polyol and polyurethane dispersions. A number of textile tests, including mechanical (tear strength (ASTM 1424) and tensile strength (ASTM D-5034)) and antibacterial, were conducted on poly/cotton plain weave fabrics after applying the synthesized dispersions by pad dry-cure methods. The hemolytic test method was used to check the biocompatibility of the synthesized dispersions. Results reveal that these finishes effectively increase the tensile strength of the treated fabric samples, such as white fabric samples, which show tensile strength values of (248, 255, 268 and 325 N from untreated 240 N) in the warp direction. The biological outcomes show the antibacterial and hemolytic activity of the dispersions are influenced by the presence of natural polyols in the dispersions. These results indicate that covering poly/cotton fabrics with vegetable oil-based polyurethane dispersions improve their tensile strength and antibacterial properties and they can replace petroleum-based polyurethane finishes.

This study introduces a novel polyurethane (PU) synthesis approach, aiming to eliminate the health risks associated with conventional methods using isocyanates and phosgene. Dehydrogenative PU synthesis is explored using iron and rutheniumbased catalysts to couple formamides and alcohols. The applied monomers can be easily prepared using formic acid in the presence of ZnCl 2 . Various parameters influencing the polymerization process are investigated including catalyst choice, monomer structure, spacer length, and solvent effects. While oligomers with low molar masses are obtained for N-alkyl formamides, N-aryl formamides yield polymers with average molar masses M n in the range of 7.60−14.4 kg/mol and polydispersities of 2.0−3.4. NMR, EDX, and elemental analysis reveal potential catalyst degradation and formation of inactive species due to ligand dissociation. Polar solvents mitigate solubility limitations, allowing for higher molar masses. The highest molar masses were achieved using RuCl 2 (PPh 3 ) 3 as a catalyst with an N-aryl diformamide and alkyl diol in an anisole/DMSO with LiBr (1 wt %) mixture (6:1), analyzed by GPC, NMR, and ESI-MS. The thermal properties of the synthesized polymers were analyzed by TGA and DSC. This phosgene-free approach represents a promising avenue for sustainable PU synthesis, addressing both environmental and health concerns associated with traditional methods.
